Abstract
Following the terminology developed in the Uniform California Earthquake Rupture Forecast, version 3 (UCERF3; e.g. Field et al. 2014), deformation models provide the specific locations, geometries and slip rates of the earthquake-producing faults explicitly modelled in the New Zealand National Seismic Hazard Model 2022 (NSHM). In this report, the derivation and characteristics of the upper-plate geologic deformation model is presented. So too is the derivation and characteristics of the two subduction interface models: the Hikurangi–Kermadec subduction interface deformation model and the Puysegur subduction interface deformation model. Details of the upper-plate geodetic deformation model are presented in a separate report (Johnson et al. 2022). (The authors)
